So twice now mom has been taken by squad to the ER. The first time she had sudden onset aphasia and a "fuzzy" feeling in her head. Lasted 12 hours. After all tests came back clear, they discharged and said she had a UTI. Second time, 7 months later, she suddenly became dizzy, aphasia, and nauseated. Bp extremely low. This time lasted 30 minutes. Again, tests clear and they said she had a slight UTI. Now mom has had whole brain radiation and also has neurogenic bladder. With the neurogenic bladder she never empties her bladder all the way meaning she always has slight bacteria indicating a mild UTI. My concern is I feel like they are TIAs. Especially considering the WBR. No one seems to agree at the hospital. But to my knowledge UTIs can cause confusion but not aphasia or really low Bp. Just wondering if anyone has experience with TIAs. What can I expect? Is a full out stroke on its way or do mini strokes just happen in some people? She is on a blood thinner due to being immobile. Thoughts?
